    摘要: According to the present invention, a rolling bearing for supporting a rotary shaft of an automotive accessory includes an inner ring, an outer ring, a plurality of rolling elements interposed between the inner and outer rings, and grease. The grease has a withstand pressure greater than a predetermined range in which plastic deformation of at least one of surfaces of the inner and outer rings and rolling elements occurs in absence of an elastohydrodynamic lubrication film of the grease on the surface. With such a configuration, it is possible to reliably avoid plastic deformation of the inner and outer rings and rolling elements regardless of presence of elastohydrodynamic lubrication films between the inner and outer rings and the rolling elements. As a result, brittle flaking is reliably prevented from occurring in the rolling bearing.

    摘要: There is provided a method and apparatus for designing a rolling bearing provided with components including rolling elements, an outer ring, and an inner ring which come into contact with each other. First, it is determined whether or not adiabatic shear bands have a potential for occurrence within at least one of the components, due to the fact that stress is applied to the components, thus causing high deformation rates in the at least one of the components to cause an unstable plastic phenomenon that brings about an adiabatic shear deformation state within the at least one of the components. Then an estimation is made such that brittle flaking resulting from the adiabatic shear bands have a potential for occurrence within the at least one of the components, when it is determined that the adiabatic shear bands have a potential for occurrence.

    摘要: It is an object of this invention to provide a compact high-power alternator for a vehicle which is good in cooling performance, efficiency, and cost without decreasing a coil resistance or using a magnet. The alternator for the vehicle includes a stator and a rotor. The rotor includes a Lundel-type iron core and a field coil provided on the Lundel-type iron core. The Lundel-type iron core has a cylindrical portion (71), a yoke portion (72), and a claw-like magnetic pole portion (73). The field coil is provided on the cylindrical portion (71). The yoke portion (72) extends from the cylindrical portion (71) in a radially outward direction. The claw-like magnetic pole portion (72) is connected to the yoke portion (72), and is formed so as to surround the field coil. The stator includes a multiple-layer iron core (32). A ratio of an axial-direction length L1 of the multiple-layer iron core (32) to an axial-direction length L2 of the cylindrical portion (71) of the Lundel-type iron core is in a range of 1.25 to 1.75. A ratio of an outside diameter R2 of the cylindrical portion (71) of the Lundel-type iron core to an outside diameter R1 of the claw-like magnetic pole portion (73) of the Lundel-type iron core is in a range of 0.54 to 0.60.
